Solution Overview

Problem

Existing smoking devices require separate purchase and manual filling of ground smokable plant matter, lacking convenience and efficient storage during transport and sale.

Innovation Solution

A dual-purpose glass container configured for storing and smoking ground smokable plant matter, featuring a smokable plant matter chamber, smoke chamber, and venturi, with a sealing cap for efficient filling and capping, allowing pre-filled units with a specific amount of plant matter.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If pre-filled smoking devices are provided, then convenience for users is improved, but storage space requirements increase

Engineering Contradiction:
Improveuser convenienceVSAvoidstorage space
Core Design Contradiction:
Ease of operationVSVolume of stationary object

Solution Approach 1:

The smoking device is designed with a nested structure where the bowl contains the plant matter chamber, which in turn contains the plant matter. The cap seals over the entire assembly. This nested configuration allows the device to be compact when not in use, reducing storage space requirements while maintaining the functionality of a pre-filled device.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Volume of stationary object

If manual filling is required, then device size can be reduced, but time and effort for preparation increase

Engineering Contradiction:
Improvedevice sizeVSAvoidpreparation time
Core Design Contradiction:
Volume of stationary objectVSLoss of time

Solution Approach 1:

The device is manufactured with pre-measured and pre-packaged plant matter already sealed inside the bowl assembly before reaching the user. This preliminary action of filling and sealing during manufacturing eliminates the need for users to perform filling operations, saving preparation time while maintaining a compact device design.

Inventive Principle:
Principle #10Preliminary action

3Manufacturing precision

If tight manufacturing tolerances are applied, then filling precision is improved, but manufacturing complexity increases

Engineering Contradiction:
Improvefilling precisionVSAvoidmanufacturing complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The device is divided into separate manufacturable components (bowl, cap, grommet) that are assembled together. The plant matter is pre-packaged in a separate container that fits into the bowl. This segmentation allows each component to be manufactured independently with standard tolerances, avoiding the need for tight tolerances on the entire assembly while still achieving precise filling through the pre-packaged plant matter container.

Inventive Principle:
Principle #1Segmentation

AI summary

The device includes a single piece of glass configured into smokable plant matter chamber, venturi structure and smoke chamber along with a sealing cap with at least one fin and a lower plug portion. The smoke chamber includes an orifice by which the user draws the smoke after combustion of the smokable plant matter in the smokable plant matter chamber that acts as a bowl for holding smokable plant matter during combustion. A cap is provided to close and seal the smokable plant matter chamber after it is filled with ground smokable plant matter and to pack and seal the ground smokable plant matter in a desire amount of compression. If the user does not consume all of the ground smokable plant matter during use, the cap can be re-inserted, and the user can store and transport the remainder of the ground smokable plant matter for subsequent use.
